drives keep dropping out?

Featured Replies

Recently been struggling with drives just dropping out and its beginning to wind me up. 


i keep getting read errors then 1 drive will get disabled and then another will just disappear without being disabled.
if i reboot i usually get the one that wasnt disabled back and i can rebuild the one that was but its becoming a real hassle rebuilding 2-3 times a week.

right before a drive drops out i will hear clicking but it is not always the same drives, the drive failures change randomly

currently its drive 3&4 (4 disabled, 3 dropped out), 2 days ago it was 1&2 (2 dropped out and 1 disabled), and before that it was 2&4 (2 disbaled and 4 dropped out) theres no real pattern to it

im not sure what if anything the diagnostics show, if there is any cause of them going offline?

no im not sure i dont, its possible, but its a good branded psu and 800w it sould be able to handle the amount of drives i have

it is though a 'gaming' psu probably not designed for 24/7 operation

Do you use power splitters?   They can sometimes cause problems, particularly if using SATA->SATA ones splitting more than 2 way.

Be careful about the term 'gaming'.  This could mean that the +12V supply is split into two segments (often called 'Duel Rail') and the larger segment of the available ampere capacity is directed to the GPU cables--- Not the Hard Disk cables.  You usually have to find the 'fine print' to figure out how the +12V is actually configured.

i dont think it was a actually advertised as a gaming psu, just i dont consider it server grade (it definately isnt)

so i have 2 strings from the psu, they come with 4 sata connectors on, i then also have 2x molex strings with 1x molex to sata adapter with 2 connectors on making 4 sata connectors.
2 of my sata strings was using 1 connector each, parity and 5, then both the molex to sata were running 2 drives each (12,34 drives)

this morning i took off 3&4 from the molex to sata and now have 3,4,5 on the 2nd sata string, im now getting read errors on 1&3 while rebuilding #4

Does this MB have onboard SATA ports? 

 

Are you using them?

 

Are you using a plugin SATA card for additional ports.   If so, what is the manufacturer and  model number and what version of firmware/software is installed?

it does and i had all my drives plugged into them, when one drops off i swap them onto an expansion card to get them back online and then back to the onboard sata when they next drop off 

ive tried the onboard and also the expansion card, same results

i know its probably power at this point but i dont understand how, the psu is 850w rated it should be plenty
the read errors happen during parity check, i hear the hard drive start clicking then i see read errors, no problem when writing.
i have also had the errors when trying to play media via plex although less common
